项目摘要

Project summary Breast cancer is the most common cancer in women, with over two-hundred and sixty thousand new cases expected in the United States in 2018 alone. There are estimated to be more than 3 million breast cancer survivors in the US due to substantial advances in detection and treatment, with this number continuing to grow. However, treatments also increase risk for long-term and late toxicities, including effects on physical and cognitive function that interfere with quality of life. One possible explanation recently proposed is that the toxicity of cancer treatments may directly accelerate the aging process in some patients, leading to earlier onset of age-related symptoms such as cognitive complaints, fatigue, declines in physical function, and lasting pain. However, this hypothesis has not been rigorously tested in clinical populations. Our study will examine the effects of common breast cancer treatments as they relate to markers of biological aging, inflammation, and reports of physical and cognitive complaints in a prospective study of breast cancer patients assessed prior to and after exposure to chemotherapy and/or radiotherapy. The proposed study will leverage an existing NCI- funded cohort of women with early-stage breast cancer assessed before onset of adjuvant therapy with radiation (RT), chemotherapy (CT), or endocrine therapy and again after completion of RT and/or CT and at follow-up visits occurring 6-, 12-, and 18-month post-treatment, with serial blood specimens for plasma, DNA and RNA analyses. In this well characterized cohort of breast cancer survivors, we propose to add the assessment of markers of biological aging using existing collected specimens and add a new behavioral assessment at 7 years post treatment to 1) examine the effects of breast cancer treatments on the biological aging process, 2) test the relationship between accelerated biological aging and cognitive and physical complaints in breast cancer patients over the follow-up period, and 3) test whether inflammatory factors mediate the relationship between biological aging and cognitive and physical complaints.

项目摘要乳腺癌是女性最常见的癌症，有超过2,6万例新病例仅在2018年就在美国预计。据估计有超过300万乳腺癌由于检测和治疗方面的重大进展，美国的幸存者继续生长。但是，治疗还增加了长期和晚期毒性的风险，包括对身体和物理的影响认知功能会干扰生活质量。最近提出的一种可能的解释是癌症治疗的毒性可能直接加速某些患者的衰老过程，导致早期发作与年龄相关的症状，例如认知投诉，疲劳，身体机能下降和持久疼痛。但是，该假设尚未在临床人群中进行严格检验。我们的研究将检查普通乳腺癌治疗与生物衰老，炎症和在对乳腺癌患者的前瞻性研究中进行的身体和认知投诉的报告并在接受化疗和/或放疗后。拟议的研究将利用现有的NCI- 在辅助治疗发作之前，评估了早期乳腺癌的妇女队列辐射（RT），化学疗法（CT）或内分泌治疗，以及在RT和/或CT完成后再次治疗后6、12和18个月发生的后续访问，血浆，DNA的系列血样和RNA分析。在这个特征良好的乳腺癌幸存者队列中，我们提议添加使用现有收集的标本对生物老化标记的评估并添加新的行为治疗后7年评估1）检查乳腺癌治疗对生物学的影响衰老过程，2）测试加速生物衰老与认知和身体的关系在随访期间对乳腺癌患者的投诉，3）测试炎症因素是否是否调解生物衰老与认知和身体抱怨之间的关系。
